  • Patent number: 12267877
    Abstract: A wireless device selects an occasion or resource unit to use for transmitting a payload within a slot that is the same as or immediately after a slot in which the wireless device transmits a random access preamble for random access to a wireless communication network. The occasion or resource unit is selected based on one or more selection criteria. The one or more selection criteria may include a type, purpose, and/or priority of the random access, of an event that triggered the random access, or of the payload. Alternatively or additionally, the one or more selection criteria may include a capability of the wireless device to transmit both the random access preamble and the payload based on the same clear channel assessment. Regardless, the wireless device transmits the payload using the selected occasion or resource unit.

  • Patent number: 12262227
    Abstract: A Cognitive Manager (CM) controls a RAN. The CM obtains from the RAN a set of local needs identifying a radio communication performance criterion that is to be satisfied. A set of neighbor needs are obtained from a neighbor CM. An event message is received from the RAN containing a radio metric that does not presently satisfy at least one of the set of local needs. A set of present neighbor improvement action drives being performed or will be performed to satisfy the set of neighbor needs, are obtained from the neighbor CM. A combination of the set of local needs, the set of the neighbor needs, the set of present neighbor improvement action drives, and the radio metric, is used to determine a local improvement action drive that is to be performed by the RAN. An adjustment report identifying the local improvement action drive is provided to the RAN.

  • Patent number: 12262320
    Abstract: Techniques for fast adaptation of PDCCH monitoring by a UE via L1 signaling in order to reduce power consumption by the UE are disclosed. A base station sends first configuration information to a user equipment (UE) via higher layer signaling (e.g. RRC) to configure downlink control channel monitoring by the UE. Thereafter, the base station may send downlink control information to the UE via L1 signaling to adapt the PDCCH monitoring by the 6 UE. The downlink control information may temporarily override or modify the parameters for PDCCH monitoring set by higher layers. The downlink control information may be send in an existing downlink control message or in a new downlink control message.
